I measured my inseam length again, and noticed I missed by almost 3 cm the first time (the ruler wasn't straight, what a genius I am...)

Actually I haven't had a change to test for reach in a real way yet, since I'm still riding with a city handlebar. I have some drops and a 100mm quill stem on the shelf, but waiting for some brifters to arrive before I get to test them. I'm just worried because the bike looks so wrong with the seatpost sky-high. Also, the stem I've got is a pretty low one, how should that fair with my kind of body proportions?
